calling it A V (this time . Also measure and record the current through the AV AV R1 AV AV R2 AV R3 R4 (total From your data , A V +A +AV R1 +AV R2 R3 R4 Compute the % -difference between (AV, + AV, +AV, + AV ) value and % -difference = Using the resistances found in part la and the rules for adding resistors in s compute the equivalent resistance of R, and R, connected in series . R = R +R +R, +R = Using your data for A V (total ) and I, determine the equivalent resistance of the R. = AV (total ) 1 / I= Compute the % -difference between these two values of R
